Typically, it would be AWG # 10 on a double 30 as it's a more readily
available breaker, but the amperage of a 4500 watt heater is 18.75 , which
makes a double 25 just fine

I looked at the wires and they say

"E18679 (UL) AWG 10 CU 2 CDR with AWG 10 Ground type NM-B 600 Volts"
and the 2 connected breakers say "25" on both of them
